Calculus Video Tutorials
http://www.integralcalc.com/
As I was studying for the forth test in Calulus 1, I found this site which seems to be an excellent resource of video examples and tutorials. The tutorials cover topics through Calculus 2.
The videos for calculus 1 cover many types of examples. I will definitely be using these for further clarification and practice.

Geometry: Two Column Proof Practice
Prove It! Practice
Two column proofs (along with the other types of proofs) require two things:
1) Familiarity with definitions and theorems
2) Practice drawing conclusions using these
This site provides guided practice for you to build your comfort with the logic based concept. Prove It! provides a significant number of general proofs that range in difficulty level.
My BEST recommendation as a former geometry student who struggled with these and NOW as a geometry math teacher who understands what is involved is to practice.
Good luck!

Imaginary Numbers
Imaginary Numbers Tutorial
As I was studying to take a trigonometry test so I can take Calculus this semester for fun (crazy, huh?), I found this site. It is a quick run through of the imaginary (complex) number rules.
What I found helpful was the practice problems. The answers are hidden until you pass the mouse over them and then they appear. Quick, easy problems that allow a student to reassure themselves that they get it.
This site also offers iPhone and Adroid apps.

Khan Academy (Videos and Practice)
Practice Problems Link
Practice Problems for ALL math levels
Khan Academy has two main resources which are amazingly
extensive. This link provides access to
problems of all levels of math concepts by topic.
There are TWO ways to search:
1)
There is a scroll
down list on the left of the screen that you can use to find any concept
you are looking for. Be sure to click “show
all” at the bottom of the list to have full access. Once you find the concept click on the name
and you will be directed to the first practice problem.
2)
A concept map is located on the right of the
screen and can be used just like Google Maps.
To search for the main idea click the screen and move it up or
down. As the map moves “south” the math topics
becomes more advanced. Once you find the
“main idea” you need, then scroll in and out using the zoom scale on the left. Zooming in will reveal more specific
categories within a context. For
example: Functions is visible from the main screen, once you zoom in, topics
such as domain and range of a function are suddenly visible as well.
Be sure to check in advance because these practice problems
are not super simple. I’m incredibly
impressed by this format. It’s thorough
and well organized!
The available concepts range from “Telling time” (early
elementary) to Calculus (High School Seniors).
There is also a statistics and probability section that goes beyond
basic pre-algebra concepts.
Example/Tutorial Videos
Khan Academy also has an extensive list of video
tutorials. The videos are broken up into
specific steps so that you can search for a particular example of a type of
question. This can be helpful for a
TEACHER wanting to demonstrate a specific process using additional perspective,
or a STUDENT who needs a refresher on how to solve a homework problem.
The videos may be searched by course subject under “Math”
and then by topic within each course.
As with anything, some videos are better than others and are
a better use of classroom time than others.
*Disclaimer: I am learning how to add pictures into the blog. Please don't judge the screen shots.
I WILL get better at adding them in the future!

Integer Operations Flowchart
Integer Operation Rules Flowchart
Integer operations are HUGE in math because once you learn them, they DON'T go AWAY! In fact, I have known many an 8th grader to get these rules confused and make mistakes that mess up the rest of their work. So, getting these correct is very important for middle school students.
This flowchart will help organize the rules in a concise manner. It's dangerous to teach students to only change a subtraction sign, because in high school that doesn't always work the same way (think distributive property!)
You can use this as a quick reference for students who need to practice perfectly.

Cool Math- Algebra
Algebra Lessons at Coolmath.com
Coolmath Algebra is a colorful site that covers an extensive list of algebra subjects. This resource is best used as additional notes/examples for a topic covered in class or advanced reading for one to be covered in class. The algebra site is organized by big topics such as exponents, polynomials, factoring, solving equations, functions etc. After you choose the "Big Topic" then you select a specific example within.
For example . . .
Big Topic: Functions
Specific Example: "What's a Function Intro"
It's set up like a textbook with chapters and sections.
Each section goes through an explanation of one example or more and then guides you to practice problems at the end.
This website is thorough and provides an alternative approach. Sometimes students need another way of seeing a process before it will click. Therefore, this is a great study source.
By the way- there is also Coolmath for Pre-Algebra, Pre Cal and Calculus, a math dictionary, puzzles, math games and math lessons by course.
Integer Operations Game
Integer Operations GAME!
This is another wonderful resource that is FREE!
Any student in grades 6-8 can find a topic to practice while playing a game. The integer game works multiplication and division facts with the integers thrown in to the mix. As a teacher, I LOVE the way the game forces the student to think and there is IMMEDIATE feedback. They have a few options to choose from, but only one is correct.
The wonderful thing is that there are MANY more to choose from. I will post the XP Math link on the pre-algebra site as well for future reference. This would make a great station, enrichment activity or homework help. Kids love online games- lets give them a brain work out in the process!
